HI ALL--I have a good question for an RME historian. I concerns a 69 with an engraved gray panel, looks like a facory installed noise blanker and the proper RME speaker, also gray. the panel and the speaker look like factory paint jobs. The 4 digit serial no begins with an S. any ideas of where it came from? (YES, i know-RME in Joliet) jack K0EWU at juno.com
